2つのテーブルを含むデータベースがあります。その1つのテーブルには、IDグループ2列があります。ここで必要なのは、テーブル内のグループデータを取得する必要があることです。
私の検索場所:
db.open();
for(int i=1;i<=5;i++)
{
if(i==1)
group1=db.getspintitle(1);
if(i==2)
group2=db.getspintitle(2);
if(i==3)
group3=db.getspintitle(3);
if(i==4)
group4=db.getspintitle(4);
if(i==5)
group5=db.getspintitle(5);
}
私のデータベースコード:
public String getspintitle(int rowId)throws SQLException
{
String sumtotal="";
Cursor cursor1 = db.rawQuery(
"SELECT spin from spinner WHERE _id=rowId", null);
// sumtotal=cursor1.toString();
// cursor1.close();
for(int i=rowId;i<cursor1.getCount();i++)
{
if (cursor1 != null && cursor1.getCount() > 0)
{ cursor1.moveToNext();
sumtotal= cursor1.getString(i);
cursor1.close();
}
}
return sumtotal;
// String spin="SELECT spin from spinner WHERE _id='rowId' ";
// return spin;
}
